To all whom it may concern Be it known that l, HARRY E. Muornvro,

a citizen of the United States, residing at Atchison, in the county of Atchison and State of Kansas, haveinvented new and useful Improvements in Railroad Grade- Grossings, of which the following is a specification.

other metal plates arranged on the outside of said rails, all of which plates shall be secured in position solely by screws,- bolts, passing through the The plates rest at their ends upon the base flanges of the rails, and are thereby given a rigid support for the loads; and, by means of the fastening bolts, lateral movement of the plates is prevented. No connectionbetween the plates and rails beingneeded, no special parts are used for the attachment, nor are additional bolt holes necessary in certain of the rails, thus enabling the crossing to be placed wherever required.

In the accompanying drawings, illustrating. the preferred form of the invention, Figure 1 is a plan view of a crossing over-a single track railroad. Fig. 2 is a cross sectional view on the line 2--2, of Fig. :l. Fig. 3 is a perspective View of one of the crossing plates, in inverted position, as used'between the rails. Fig. t is a similar view of one 'of the plates designed to be placed against theoutside of the rails to form the approach to the track. Fig. 5 is an enlarged sectional view oj ffone track rail and elevations of parts of two plates supported on the rail flanges.

The track rails are indicated by A and the cross ties by B, and do not diflerirom such as are in common use. Between the'rails A and extending transversely of the [track are placed a plurality of rectangular plates 10 which may be made of cast iron or steel, pressed steel or other suitable metal. Each of these plates is sufiiciently long to extend from rail to rail and has a width of about one half its length. The plates have a slight regular convex curvature in a longitudinal direction for the greater part of their length, but a quick downward and outward. bend ii at their ends serving to lower these ends so that they shall. pass under the heads of the rails.v A channel 12 is thus formed at the inner or gage edges of the rails A to proylde clearance for the wheel. flanges of pass mg trains. A depending flange 13 is formed on each end-of each plate 10, and a. like flange let on each side thereof; and if found desirable or necessary a longitudinal rib 15 may be formed between the side flanges 14. When in position the end flanges 13 of the plates 10 rest upon the inner base flanges 16 of the rails A and hold the plates out'of contact with the ties B. Arigid support is thus given to the plates which, being free from the cross ties, cannot cut into them under traffic and be loosened. Lag screws 17, spikes, or other suitable fastenings pass through holes 18 in thecorners of the plates, and are driven into the ties. The holes 18 are countersunk to bring the heads of the fastening means below the surfaces of the plates. The plates may be smooth on their wearing surfaces or roughened. They may also be provided with holes through which dirt may work.

The approaches to the track on each side are made of several rectangular metal plates 19, preferably of a length equal to the width of two plates 10. The plates 19 are placed end to end parallel with the rails A. with one side in contact with the outer edge of the rail. The width of these plates may "vary, but by preference; is less than their length. The inner edge of each plate 19 has an under flange 20 which rests on the outer edge 21 of the adjacent-rail A; and also two longitudinal ribs22 reaching downward to the cross ties, and which-resting thereon assist the flange 20 in supporting the plate 19. The sides of the plates 19 extend beyond the outer ribs 22 and bear upon the material forming the street or highway their upper surfaces being continuous with the ground surface. These approach plates 19 may, as shown, be given a slight downward inclination away fromthe rails if the grade. of the highway demands it. Lag screws 23, or otherv fastening means passing through holesQ l at the inner-corners of the approach plates, secure said plates to the ties as in the case of the plates 10. The plates 19, if desired, may be roughened andperforated. When the crossing intersects, a double track road, or where" several tracks lie par:

allel to each other, the space between the tracks maybe filled with plates similar to the described plates 10.

The width of the crossing and the number of plates used will depend upon the amount of traflic passing over the road No fitting with the wishes of the skilled mechanic,'and

such changes as do not involve invention I consider as within the scope of my claims.

Having thus described my invention, I claim a I 1. A railroad crossing comprising a plurality of metal plates extending transversely between the rails of the track and supported at their ends on the rail flanges, a plurality of plates adjacent to the outer sides of the rails and supported at one side by the outer flanges of the rails, and means for securing the plates to the cross ties. I

2. A railroad crossing comprising a plurality of metal plates extending transversely between the rails of the track and supported at their ends abovethe cross ties and out of contact therewith by \the rail flanges, a plurality of longitudinally extending plates ad: jacent to the outer sides of the rails and supported at one side by the outer flanges of said rails, and means for securing each plate solely to the cross-ties 3. A railroad crossing comprising a plurality of metal plates extending transversely between the rails of the track and supported by depending flanges on the ends of said plates bearing on the rail flanges, a plurality of plates adjacent to the outer sides of said rails and supported on theouter rail flanges by a depending flange, and means for securlng the plates to the crossties of the track independently of the rails.

t. A railroad crossing comprising a pluralityof metal plates extending transversely only at their ends on the rail flanges, and means for securing said platesto the cross ties. f j l i 5. A railroad crossing comprising a plunwasat rality of metal plates extending transversely between the rails of the traclnand supported I at their ends on the rail flanges, the ends of said plates being depressed to provide 'clearance for the wheel flanges of passing trains, a plurality of plates adjacent to t e outer sides of the rails and supported at one side by the outer flanges of the rails, and means for securing the plates to the cross ties.

6,. A railroad crossing compris ng a plurality of metal plates extending transversely between the rails ofv the track'andsup orted solely on the rail flanges by depending anges on the ends of saidplates, said ends being so rails and provlde clearance for the wheel flanges of movin trains, 1 plurahtyof approach plates adJacent to the outer sides of the rails and supported at one side by the rail flanges, and means for securing the plates to the cross ties.

-7. A crossing plate for railroad crossings depressed as to pass beneath the heads of the comprising an integral rectangular metal 9. A railroad crossing comprising a plurality of curved metal plates extending transversely between the rails of the track and having depending flang'es on their'ends adapted" to bear on the rail flanges and support the plates above'the cross ties, a plurality of plates adjacent to the outer sides of the rails, each plate having a depending flange along one side edge that bears upon the outer rail flange and supports the plate atsaid'side, all of said plates having perforations through the corners near the rails, and-bolts or screws passing throu h said perforations into the crossties and orming the sole means for fastening the plates in position. i' t lntestimony whereof I afiix my signature v v in presence of two Witnesses. between the rails ofa track and supported 4 HARRY n.
